Spectra7 Microsystems Inc. announced that it will partner with Volex plc to demonstrate Spectra7's new 112G PAM4 GaugeChanger™ chip intended for next generation 800Gbps data center interconnects at this year's annual DesignCon Conference and Exhibition being held in Santa Clara, CA from February 1-2, 2023. The demonstration will highlight a Volex 3-meter 28AWG Active Copper Cable with Spectra7's GC1122 ICs. The GC1122 is the latest addition to the GaugeChanger™ product line and extends the data rate from 56 to 112Gbps per lane.

Since the GC1122 is analog and highly linear, dynamics such as line rate adjustment, multi-level signaling, intermittent line silence, transmit pre-emphasis or amplitude adjustment and receiver adaptivity are fully preserved. GC1122 chips are now sampling to leading cable partners and end customers. Spectra7's GaugeChanger™ is an innovative technology that allows copper to extend much longer lengths without the cost and power penalty of optics or DSP based retimed copper solutions.

It works equally well at 25G NRZ, 56G PAM4 and 112G PAM4 signaling, enabling Ethernet interface standards of 100, 200, 400, 800Gbps and 1.6Tbps.
